Fire Fighting Instructor Interview Question:

Do you know what is a DRY fire sprinkler system?

Submitted by: Muhammad

Used where a frost risk may arise, the dry fire sprinkler system is constantly charged with compressed air, which holds the fire sprinkler valve in closed position. When a fire sprinkler head is activated, the air pressure is lost, the valve opens and water flows into the system and on to the fire.

A dry fire sprinkler system is commonly installed in areas where the ambient temperature is at or below 32 degrees F.
